Solution overviews (can be called conceptual architectures, solution outlines, conceptual designs, preliminary solution architectures, solution briefs, etc.) Stephen J Pratt FBCS, offers his personal reflections on how COVID-19 has - and continues to - change working practices, management, expectations and conventions. Enterprise architecture artifacts (or EA artifacts) are separate documents constituting enterprise architecture. However, all real EA artifacts can still be mapped in a similar manner to one of the six general types of EA artifacts defined by the CSVLOD taxonomy. describe specific IT projects in a brief business-oriented manner, usually including their high-level architectures, expected business value, estimated costs, risks and timelines. Principles are the most ‘classic’ EA artifacts related to the considerations general type (business-focused rules). Permanent EA artifacts are created once and then updated when necessary according to the ongoing changes in an organization and its business environment. Enterprise architecture (EA) practice implies developing and using specific EA documents (artifacts) to facilitate information systems planning. This paper uses the concept of boundary objects to derive hypotheses for the design of Enterprise Architecture (EA) artifacts. Therefore, the full set of EA artifacts used in successful EA practices is not limited to these eight EA artifacts. Boundary objects are a useful concept to understand the coordinative role of artifacts in practice, making them a proper vehicle to analyze how EA artifacts can be designed to support communication and coordination during enterprise transformation. They help senior business stakeholders estimate the overall business impact and value of proposed IT projects and make informed investment decisions regarding these projects. TOGAF. EA artifacts related to this general type identified in organisations include platform architectures, relational diagrams, application portfolios, integration contexts, system interaction diagrams, inventories, asset registers, IT systems value maps, one page diagrams, enterprise technology models and all sorts of technology roadmaps. Like all EA artifacts related to outlines, solution overviews represent benefit, time and price tags for specific IT projects. They can be considered as key elements and cornerstones of an EA practice. Like all EA artifacts related to standards, TRMs and guidelines represent proven reusable means for IT project implementation. Popular EA books, and frameworks, e.g. The concepts discussed in this section have been adapted from more formal definitions contained in ISO/IEC 42010:2007 and illustrated in Figure 35-1. Landscape diagrams (used under very diverse titles, including system interaction diagrams, relational diagrams, platform architectures, one page diagrams, integration contexts, etc.) 2011. Popular EA books, and frameworks, e.g. A hyperlink will be created automatically. Like all EA artifacts related to considerations, principles represent the overarching context for information systems planning. Different EA artifacts are used by different actors at different moments for different purposes and fulfill different roles in organizations. Landscape diagrams are usually maintained by architects and updated at the completion stages of all IT projects modifying the IT landscape. to pretty low-level details (e.g. business or IT capabilities, overarching rules, executive-level considerations, etc.) Figure 1 shows the schematic representation and mapping of the eight essential EA artifacts actively used in most established EA practices. How to implement a clean, green data centre strategy, How keyloggers work and how to defeat them. Enterprise architecture (EA) practice implies developing and using specific EA documents (artifacts) to facilitate information systems planning. Purely textual EA artifacts contain only plain text. Purely graphical EA artifacts contain only diagrams and models sometimes created using special modeling languages or notations. The "architecture" of a system is the system's fundamental organiz… They may be either developed at once in a proactive manner, or produced reactively on an as-necessary basis, i.e. Enterprise architecture (EA) practice implies developing and using specific EA documents (artifacts) to facilitate information systems planning. After being developed these EA artifacts are constantly used, continuously maintained and occasionally discarded when become irrelevant. Bloomington, IN: AuthorHouse. The titles provided above are merely the most popular titles for these EA artifacts, but the same EA artifacts can be used under different titles in different organisations. Here I explain how these EA artifacts map to the generalised CSVLOD taxonomy. accumulated in organizations gradually over time. But what EA artifacts then are used in real successful EA practices? achieved and formalized agreements between various stakeholders regarding the desired future course of action. Enterprise Architecture Planning: Developing a Blueprint for Data, Applications and Technology. They “live” and evolve together with an organization. ), EA artifacts can cover different organizational scopes. Since objective facts are normally not discussable and do not require any real decision-making, these EA artifacts may be developed or updated solely by specific actors, but represented in formats convenient for their future users. Kotusev, S. 2016. You may redistribute it, verbatim or modified, providing that you comply with the terms of the CC-BY-SA. Essentially, an EA practice revolves around using specific sets of EA artifacts for improving communication between different actors. 'TOGAF Version 9.1,' G116, The Open Group. Descriptions contained in EA artifacts can range in their granularity from very high-level abstractions (e.g. Enterprise architecture consists of multiple different artifacts providing certain views of an organization and the available enterprise architecture literature offers a number of comprehensive lists of artifacts that can be used as part of an enterprise architecture practice. Temporary EA artifacts are created at specific moments for particular purposes, used as intended and then immediately discarded or archived. They are transitory, single-purposed and disposable.
